SECTION 7 DIAGNOSTICS AND TROUBLESHOOTING
________________________________________________________________________
7-3
Problem Isolation Procedure:
Use the following sequence to determine the most probable
cable:
1.
With no sensor connected, run DSC Self Test (see Section 7.2.2 “BISx Checkout
Procedure):
•
If test fails or will not start, or the BISx is not recognized, the Monitor cable is
likely suspect. This failure may also be related to a PCB problem in the BISx in
which case the BISx must be replaced.
•
If test indicates PASS, continue to step 2.
2.
Connect Sensor Simulator or Test Simulator. Run Sensor Check (see Section 7.2.3
“PIC Chekcout Procedure)
•
If failure is noted, swap PIC with known good PIC cable and run again.
•
If failure repeats, the BISx or the BISx Bulkhead Connector is suspect. This
failure may also be related to a PCB problem in the BISx in which case the BISx
must be returned to Aspect for service.
